SHUTTLE-BOX MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 411,408, datedSeptember 17, 1889.

Application filed February 14, 1889. Serial No. 299,870. (No model.)

them, and rotating shuttle-boxes, an example,

of which is contained in United States Patent No. 97,106, being usedchiefly in Weaving carpets. In this class of loom prior to my inventionit has been customary to mount the bearings for the rotary shuttle-boxesin the same frame which carries the drop shuttle-boxes, this requiringthat both sets of boxes be moved together, the vertical movements ofboth sets of boxes at one end of the loom being derived from one and thesame lever actuated by a cam.

In a loom of the class referred to, where both kinds of boxes aremounted in and made movable vertically together in one frame, the weightto be moved and the distance are such that necessarily the speed atwhich the loom may be run is limited.

In carpet-weaving it frequently happens that the pattern requires notover four colors, or the number of colors which may be put in by thedrop shuttle-boxes alone; but in looms heretofore made the rotary boxeshad to be raised and lowered in unison with the dropboxes,even thoughthe shuttles in the rotary boxes were not required in the production ofthe pattern then being woven, and this extra duty of the loom results inunnecessary expenditure of power and wear of bearings. In my experimentsto improve this class of loom I have mounted the shaft or journals forthe rotary shuttle-boxes in a frame which may be moved vertically on orwith relation to the frame which guides the drop shuttleboxes, both theframe carrying the rotary shuttle-boxes and the frame carrying theseries of drop shuttle-boxes being provided with independent means bywhich to raise and lower or move them vertically in proper time or orderto place opposite the race of the lay either one of the cells of thedropboxes or one of the cells of the rotary box. In this manner, when acarpet or other fabric is being woven which requires only the number ofcolors which may be readily supplied from the drop-boxes alone, it ispossible to leave the series of rotary boxes down in their lowestposition, or, in other words, the vertical movements of the framecarrying the rotary boxes may be suspended.

\Vhen more colors are needed in the pattern than can be readily put infrom the drop-boxes, then in my improved loom the series of rotary boxesmay be readily elevated, and any of its shuttles may be employed for oneor more picks, and the rotary shuttle-box be then lowered and be leftdown for any desired number of picks.

In my improved loom the order of movement of the drop shuttle-boxes atboth ends of the loom is controlled by a patternsurface at one end ofthe loom, the shuttle-box levers at both ends of the loom employed tooperate the drop-boxes being actuated by a shaft ex tended across theloom, and in the form in which my invention is herein embodied the endof the loom opposite that containing the pattern-surface employed toeffect the changes in the drop shuttle boxes has been provided with anauxiliary pattern-surface, which, as shown, derives its movementintermittingly from a cross-shaft, the said pattern-surface indicatingthe times of movement and of rest of the levers employed for movingvertically the frame which carries the journals of the rotary boxes.

In my invention, as herein shown, I have represented the dropshuttle-boxes as having four cells, and the shuttle-box moving mechanismco-operating with the drop-boxes is so devised in well-known manner asto enable any one of the said cells to be brought to the level of therace of the lay, as required; but when the pattern requires for itsproduction more colors than can be supplied from the drop shuttle-boxesalone and the rotaryboxes have to be called upon to supply thedeficiency, then the order of movement of the dropboxes has to besomewhat changed, as it will be obvious that the drop shuttle-boxes haveto be raised higher than before far enough to leave proper space inwhich to elevate the rotary boxes to the level of the race, andconsequently the upper box of the series cannot be used. To do this, Ihave made the connecting-rod between the lever actuating the dropshuttle-boxes and the drop-box rod so that its effective length may bechanged, it in effect being lengthened when both the drop-boxes androtary boxes are to be employed together, the drop-boxes at such timebeing lifted higher.

One feature of my invention consists, essentially, in a loom containingthe following instrumentalities, viz: a series of drop shuttleboxes, aguide therefor, and a series of rotatable shuttle-boxes, an independentframe in which the said rotatable shuttle-boxes are mounted, and meansto move the said frame independent of the means employed to move thedrop-boxes, as will be described.

Other features of myinvention will behereinafter described, andspecified in the claims at the end of the specification.

Figure 1 is a partial left-hand end elevation of a loom embodyingmypresent invention, the upper part of the frame-work being omitted, theuppermost cell of the series of drop shuttle-boxes being broken off, thelowermost cell of the drop shuttle-boxes being supposed to be inoperative position opposite the raceway of the lay, (shown onlyin Figs.2 and 3,) the rotary box being supposed to be in its lowest position.Fig.1 shows the stand for supporting the intermediate gear, to bedescribed. Fig. 2 is a partial right-hand end view of the loom shown inFig. 1, but with the lay added, the parts being, however, in a differentposition, for in Fig. 2 the drop shuttle-boxes have been lifted anotherstep and two of the cells at the top are broken oif, the rotary boxbeing supposed to be down in its lowest position, the shaft 0 being insection back of the worm C. Fig. 3 isapartial rear elevation of theparts represented in Fig. 2 at the left of the dotted line m. Fig. at isa partial plan View of parts at the right of the dotted line at, Fig. 2.Fig. 5 is a View showing a part of the devices omitted from Fig. 1 atthe left side of the loom, the said devices being employed to operatethe pattern-surface for the drop shuttle-boxes. Fig. (i is a sectionaldetail of the pattern-surface for the rotary shuttle-box; Fig. 7, adetail showing the inner end of one of the rotary shuttle-boxes, withits pins and the pawl to engage the said pins when the rotary box is tobe rotated in one or inthe opposite direction. Fig. 8 is a crosssectionof the hub D in the dotted line y y thereon, Fig. 4; and Fig. 9 is adetail, but on a smaller scale, of the stud-carriers, connectin g-rods,toothed cranks, secondary lever, and arm and shaft employed to move thedrop shuttle-boxes at the opposite or right-hand side of the loom, thesaid devices lying behind the parts for moving lever E.

In the form in which myinvention is herein shown as embodied the seriesof drop shuttle-boxes and the frame carrying the rotary boxes are madeto slide up and down in guideframes at opposite sides of the loom,thesaid guide-frames being connected to and adapted to vibrate in unisonwith the lay; but I desire it to be understood that the said dropshuttleboxes and frame carrying the rotary boxes may be supported in anyother usual form of guide-as, for instance, in some looms, as in UnitedStates Patent No. 211,718, wherein the guides are attached to theloom-frame rather than to the lay.

The frame-work A of the loom (but partially shown) is and maybe of usualshape to support the working parts.

The power-shaft A, its beveled pinion A the toothed gear A on the crossor picking shaft A, the toothed gear A driven by it and fast on thecrank-shaft A, and in practice joined to the lay A by usualconnecting-rods, are and may be all as common to looms now in use.

Viewing Fig. 3, it will be seen that the journal A on which the sword ofthe lay turns, is extended through the loom-frame and forms one of thepivotal points for the guide-frame B, which guides the drop shuttleboxframe B, the opposite side of the guideframe B having a pivot B in astand B The frame B and the parts carried by it are alike at oppositesides of the loom-frame.

The lay and guide-frame, as herein shown, are bound together by a brace,as B so that they move forward andbackward in unison in usual manner foreach pick; but my invention as to the independent movements of the dropshuttle'boxes and of the rotary shuttle-boxes might be practiced toadvantage in a guide-frame substantially such as in United States PatentNo. 211,718 referred to, wherein the guide-frame is stationary ratherthan vibrating with the lay.

The frame B has a suitable guide, in oron which slides the frame B,carrying the shelves or cells of the series of drop shuttle-boxes.

Herein it will be supposed that the drop shuttle-boxes have four cells;but in the drawings, Fig. 1, the uppermost cell of the series isrepresented as broken off to save space on the drawings, two said cellsbeing broken off in Fig. 2 for a like purpose.

The lower part of the frame B, as shown best in Fig. 3, has connected toit by twolike rods B a cross-bar B to which is attached the box-rod Bhaving its lower end extended through a hole in a bracket B carried byor forming part of the fi ame B. The box-rod B has a stud B extendedfrom it, over which; when both the drop and rotary shuttle-boxes, to bedescribed, are to be employed together for the production of the patternbeing woven, is fitted the upper end of the connecting-rod B, the saidconnecting-rod having, however, as herein shown, a second hub, as B,which may be applied to the said stud to thus shorten the effectivelength of the rod B, such being necessary when only the dropshuttle-boxes are to be used in the production of the pattern, for inthis latter case all the four cells of the drop-boxes may carry each ashuttle.

The connecting-rod B instead of having the two holes or hubs referredto, maybe constructed in other usual manner, whereby its effectivelength may be readily changed when required. The connecting-rod B isjointed to the forward end of a drop-box lever B, pivoted at B on theloom side. The rear end of the lever B is connected by a link B with amain lever E, herein shown as of elbow shape and mounted to turn freelyupon a stud E, supported in suitable bearings forming part of a frame orbracket 45, secured to the loom side. One arm of the main leverhaspivoted upon it at e a secondary lever F, it having near its oppositeends two flat faces, which are acted upon respectively by pins or studsextended from two stud-carriers G G, joined, respectively, byconnect-ingrods m m to like toothed cranks g, each mount-ed upon a likevibrator f, each vibrator being connected by a suitable rod,as h, which,extended upwardly,

is attached to one of a series of like fingers 7L, to be described.

Commencing with the lever E, just above referred to, and ending with thefingers h, the parts referred to are substantially as in United Statesapplication, Serial No. 263,272, filed February 7, 1888,and alsosubstantially as in United States Patent No. 336,623. As the fingers hare acted upon by the usual pattern cylinder upon which they rest, thesaid toothed cranks g are raised or lowered, so that they may be engagedwith and rotated by one or the other of the partial gears a or (1',common to the said PatentNo. 336,623,

the said gears being rotated in opposite directions by the usual trainof gearing between them.

The shaft containing the gear (1 in this present instance of myinvention is shown as deriving its usual motion by or through a gear, as70, common to my said application, it being engaged and rotated by agear 7-3, (shown by dotted lines in Fig. 1,) the gear 73 being anintermediate, which derives its motion from a toothed gear H, which isfast upon the opposite end of the shaft A, before de scribed as havingfast upon it the gear A In line with the stud E there is a shaft 47,common to my said application,and but partially shown in Figs. 4; and 9,the end of the saidv shaft at the right-hand end of the loom being inpractice supported in a suitable box or bearing. The shaft 47 at theleft-hand end of the loom has fast upon it an arm E (shown partially inFig. 1, by breaking away part of the lever E, and in Fig. 7,) the lowerend of the arm E having pivoted upon it a like secondary leverF, whichis acted upon by like stud-carriers G G, having jointed to themconnecting-rods like m and m, which in turn are jointed to like toothedcranks g, the said toothed cranks in their partial rotations in one orthe other direction serving to rock the shaft 47, it having at itsopposite end or at the right-hand side of the 100111 (see Fig. 4) acrank or arm, as 48, which is connected by a link, as t, with a stud atthe inner end of the drop-lever 13 like the lever B, before referredto,the said lever B having its'fulcrum on a stud B and being connected, asdescribed of the lever B with the box-rod depending from the lower endof the frame carrying the series of drop shuttle-boxes and located atthe right-hand end of' the loom.

As one means of actuating the pattern-surface, which may be of any usualconstruction and upon which rest the fingers h, I may provide thecrank-shaft (see Fig. 5) with a pin-wheel, as D which in its rotationwill actuate intermittingly astar-wheelD mounted upon a suitable studand having an attached beveled pinion D the said beveled pinion engagingtwo like beveled pinions D D", loose on the pattern-actuating shaft D,it having at its upper end a beveled pinion D which engages a beveledpinion h mounted upon a suitable stud and having a connected gear h,which engages an intermediate gear 72. rotating it so that the latter inengagement with a suitable gear on the pattern-shaft h", common to mysaid application, rotates the pattern-surface.

I do not desire to limit myinvention to the means employed for rotatingthe pattern-surface for moving the fingers-71., as 1 may use instead anyother usual actuating means. The clutch-collar D splined on the shaft Dand controlled by the lever D may be engaged with either wheel D or D",according to the direction in which it is desired to rotate the shaft DThe devices herein described for such purpose are however, as in my saidapplication.

Referring to Figs. 2 and at, it will. be seen that the shaft A outsidethe gear A has fast upon it a hub D, having at one side of itnear itscenter a substantially semicircular-series of teeth 100, the hub at eachside of the said teeth being cut away somewhat, as at 2 3, to leavespaces which extend about the said hub for substantially one hundred andeighty degrees, the inner end of the hub being, however, left to presenta smooth surface, as 4, extending entirely aboutit, upon which may bearthe concaved face of one of the locking projections 5, connected to orforming part of a toothed gear 6, fixed to a sleeve-like hub 7, mountedto slide freely upon a stud 8, fixed in a suitable stand, as 9, attachedto the loom side. The hub 7, near its outer end, has an annular groove,which is embraced by pins at the forked upper end of a lever 10, (bestshown in Figs. 2, l, and 6,) the said lever being pivoted on a stud 12in a stand 13, secured to the loom side. This lever 10, as best shown inFig. 6, has three arms, two of the arms, as 10 10 extending over andunder the pattern-surface 0, fast upon a shaft 0', extended. through atubular bearing 0 and ICC having fast upon its opposite end awormtoothed gear which is engaged and rotated by aworm 0 fast on a shortshaft C mounted in a bearing 18, forming part of a suitable stand 25 thesaid shaft having at its inner end a toothed pinion 19. The pinion 19 isengaged by the teeth 100, referred to as attached to the hub secured tothe shaft A the said teeth rotating the said pinion 19 once during eachrotation of the shaft A, and consequently moving the pattern-surfaceintermittingly. The short shaft C has fast upon it a locking projection22, (see Fig. 2,) having 'a concaved face, the said locking projection,as soon as the teeth 100 run out of mesh from the pinion 19, meeting thecon vexed face of the hub D, the shaft 0 so long as the projection 22bears against the hub, remaining at rest, as will be well understood.The pattern-surface C has usual rolls, projections, and spaces tovibrate the lever 10, and thereby move the hub '7 longitudinally, andwith it the gear 6 and locking projections 5.

When the parts are in the position shown 1 in Fig. 4, with one of thelocking projections, as 5, bearing against the unbroken periphery 4 ofthe hub D, the gear 6 cannot rotate, and

consequently the gear D, with which it is engaged, remains at rest; butwhen it is desired to rotate the gear D, the time of such rotationdepending upon the pattern-surface, the hub 7 is drawn in the directionof the arrow, Fig.

4, far enough to place the gear 6 in the range of motion of the teeth100 of the hub D, the latter then acting to give the gear 6 ahalfrotation and leave it at rest, one of the locking projections 5coming against the cylindrical part of the hub D as the teeth 100 runout spring-held pin 52, (shown by dotted lines,

of mesh with the gear 6.

The gear 6 constitutes what I call a clutchgear,and is of the samediameter as the gear D, so that each half-rotation of the gear 6 causesa half-rotation of the gear D.

The gear D has a crank-pin 27. The crankpins 26 and 27 are connected,respectively, by links 28 and 29 with suitable studs secured to orprojecting from the like levers 3O 31, each pivoted, as at 32 or 33, atits rear end.

As will be understood, a semi-rotation of the shaft will move levers 3031 up or down, according to which half of the circle the crankpin istraveling in.

The levers 30 and 31 being alike, I shall for sake of brevity describethe connections between but one of them with the frame carrying therotating shuttle-boxes, and I shall select for such illustration thelever 31 at the right-hand side of the loom.

Each rotary shuttle-box M, as herein shown, has five cells or shelves.The shaft or journal of each rotary shuttle-box is mounted in aslide-frame M, having ends to run in or on suitable ways of theguide-frame B. Each slide-frame M has connected to it a suitable Thegear D is fast on a shaft 25, extended across I the loom-frame andhaving upon its opposite end (see Fig. 1) a crank arm and pin, as 26. I

box-rod M which is extended down through a hole in the guide-plate Bbefore referred to. Each box-rod M has a suitable pin or stud M which isengaged by the upper end of a link, as M which in turn is connected toone of the levers 31 or 30, so that as the said levers are moved thesaid slide-frame M, containing the rotary shuttle-boxes, is raised andlowered in the proper time and order, and it will be noticed that thismovement of the slide-frame 1W is entirely independent of the movementof the slide-frame B, each frame deriving its own movement ofreciprocation in a vertical direction through independent devices and inaccordance with the demands of the pattern-surface.

The gear H on the shaft A engages an intermediate gear 30, mounted on astud 31 of a stand 32, adjustably secured to the loom side by a suitablebolt extended through a slot, as 33, in the stand. (See Fig. l The gear30 has secured to or forming part of it a pinion 34, which engages atoothed gear 35, mounted on a stud 36, and having attached to it a cam37, the said cam in its rotation acting upon a roll 38 at one end of alever 39, connected to a rock-shaft 40, extended across the loom andhaving at the opposite side of the loom an arm The front end of the arm39 and of the arm 40 are joined in like manner to like double pawls 41,(see Fig. 7,) having projections 42 43, each pawl having connected to ita link 44, which is in turn jointed (see Fig. 1) to an arm 45 of arockshaft 46, mounted in suitable bearings of a stand 50, provided, asherein shown, with a notched plate 51, which is adapted to be engaged inone or the other of its notches by a Figs. 1 and 2,) inclosed in ahandle 53 or 53*, projected from the shaft 46, the movement of the saidhandles in one or the other direction effecting the movements of thedouble pawls 41, so that one or the other of their projections 42 or 43will engage in the Vertical movement of the pawl a pin, as 58, at one orthe other side of the center of motion of the rotary shuttle-boxes, soas to turn the said boxes about their journal or center in one or theother direction, according to the requirements of the pattern beingwoven.

In the position in which the parts are shown in Figs. 2 and 7, Fig. 7being supposed to be a View taken from the main side A of the loomoutward, it will be seen that the projection 43 is underneath one of theproj ections 58, so that when the pawl 41 is raised or moved in thedirection of the arrow thereon, Fig. 7, it will rotate the shuttle-boxin the direction of the arrow 60, Fig. 7. It will be readily understood,however, that should either handle 53 or 53 be moved toward the front ofthe loom the projection 42 Would stand under one of the pins 58 andwould effect the rotation of the rotary shuttlebox M in the oppositedirection.

In case it should be desired to move the IIO rock-shaft etfi by orthrough a pattern-surface, then the said rock-shaft may have projectingfrom it iii-opposite directions arms 61, which may be, connected bysuitable cords, as 62, with any usual or suitable Jacquard contrivanceto shift the rock-shaft and move the pawl 41 into either of its twopositions.

To prevent the overrunning of the rotary shuttle-boxes, each shuttle-boxis provided at one end with suitable pins, as 65, which are acted uponby a head 66 at the upper end of a slide-rod 67, extended throughsuitable guides in the slide-frame M and normally held upward by aspring, as 68, surrounding the said rod and acting upon a collar 69,secured to the rod.

By changing the gears 30 34 for gears of other size the speed ofrotation of the gear 35 and its cam 37 may be increased or decreased, soas to operate the lever 39 and pawl 41 more or less frequently, thatdepending upon the frequency with which it is desired to rotate therotary shuttle-boxes.

I have omitted from the drawings the picking mechanism, shuttle-boxbinders, breast beam, warp-beam, take-up, &c., as in practice the saidparts forming the usual accompaniments of a powei loom will and may beof usual construction.

I have described the crank-pin 26 as deriving its intermitting rotationfrom the shaft 25; but it will be obvious that I may connect the saidcrank-pin with a gear, such as the one D, described as carrying thecrankpin 27, and in such case I may provide at the left-hand side of theloom a gear, as 6, and operating devices therefor, as at the right-handside of the loom. (See Fig. 2.) In this way the rotary shuttle-boxes atthe opposite sides of the loom may be actuated vertically independently.

The crank-shaft A is shown as prolonged at the right-hand side of theloom, where it has applied to it the hand-wheel A I claim- 1.
